When in use, the airflow collected by the dust collection hood is sent into the smoke and dust channel through the pipe, fully contacts with the water mist generated by the water mist generator, absorbs water, automatically sinks into the dust removal pool, and realizes the separation from the gas. After the dust and gas are separated , the gas enters the chimney to achieve up-to-standard emissions. The utility model has reasonable design and compact overall structure, can effectively collect smoke and dust in smelting waste gas, reduce metal loss and improve process environment.

Description

Water mist dust collector

                      

The utility model relates to a water mist dust collection device, which belongs to the technical field of environmental protection equipment manufacturing.

Background technique

The existing dust collection methods mainly include water curtain dust collection, vortex dust collection, cloth bag dust collection, electrostatic dust collection, etc. The equipment cost and operating cost are relatively high, and the dust-carrying airflow flows from the dust collector The inlet enters, and after being treated, it is quickly discharged from the outlet. Due to the short stay time of the airflow in the dust collection device, the smoke and dust cannot fully contact with the dust collection device, and the dust is often not collected cleanly. Part of the smoke is still discharged with the airflow, causing environmental damage Therefore, for large smelting enterprises, it is difficult to fundamentally solve the environmental pollution caused by smoke and dust.

Contents of the invention

The purpose of the utility model is to provide a water mist dust collection device with reasonable design and high dust collection efficiency.

The utility model is a water mist dust collection device, which is characterized in that it includes a dust removal pool with a smoke channel and a water mist generator, a deflector placed at one end of the dust removal pool and a pipeline with a dust collection cover, placed at the other end of the dust removal pool Demister plate and induced draft fan with chimney. When in use, the airflow collected by the dust collection hood is sent into the smoke and dust channel through the pipe, fully contacts with the water mist generated by the water mist generator, absorbs water, automatically sinks into the dust removal pool, and realizes the separation from the gas. After the dust and gas are separated , the gas enters the chimney to achieve up-to-standard emissions.

In addition to the dust-removing pool, there may also be a circulating pool connected to the dust-removing pool and the water mist generator. The cleaned water in the dust removal pool can be recycled.

The water mist generator can be composed of water pipes with nozzles evenly arranged in the smoke channel.

The utility model has reasonable design and compact overall structure, and has the following outstanding advantages and positive effects compared with the prior art:

1. Less investment, small footprint, low operating cost, can be placed below the ground as a whole, without affecting the overall layout of the workshop;

2. The dust collection is clean, which can realize the discharge of smoke and dust up to the standard, which is beneficial to environmental protection;

3. The metal in the soot can be recycled and utilized, reducing loss and saving costs.

The utility model can be used in the smelting process of various copper, aluminum and other metals or alloy materials, as well as other industrial furnaces, and can effectively collect the smoke and dust in the smelting exhaust gas, reduce metal loss and improve the process environment.

Detailed ways

The utility model is mainly composed of a dust removal pool 7 with a smoke and dust channel 3, a water mist generator 5, and a circulating pool 8, a deflector 4 placed at one end of the dust removal pool 7, a pipe 2 with a dust collection cover 1, and a dust removal pool 7. The defogging plate 6 at the other end, the induced draft fan 9 with the chimney 10 etc. constitute. The circulating pool 8 communicates with the dedusting pool 7 and the water mist generator 5 respectively, and the water mist generator 5 is composed of water pipes with nozzles evenly arranged in the smoke passage 3 .

When in use, start the induced draft fan 9, the airflow collected by the dust collection hood 1 passes through the pipe 2, and is sent into the smoke and dust passage 3, and the deflector 4 makes the smoke and gas mix evenly after the smoke and dust enter the smoke and dust passage 3, and then enters into the airflow formed by the water mist. The water mist generated by the generator 5 is fully in contact with the water mist. After the smoke dust contacts with the water mist, it absorbs water, increases in weight and automatically sinks, and enters the dust removal pool 7 to realize separation from the gas. After the dust and gas are separated, the gas passes through the defogging plate 6 to remove the moisture in the gas, and then enters the chimney 9 to achieve standard discharge; after the smoke enters the pool 7, it deposits at the bottom of the pool and is cleaned regularly, and the water without smoke and dust flows into the circulating pool 8. After being pressurized by a water pump, it is sent to the water mist generator 5 to generate water mist.
